IMPROVEMENT IN CARRIAGE-PAINTERS EASELS'.

Specification-forming part of Letters Patent No. 160,959, dated March16, 1875; application filed January 25, 1875.

To all whom it may concern:

Be it known that I, ALVARO GALATIA RYKERT, of Attica, "in the county ofWyoming and State of New York, have invented certain Improvements inAdjustable Platform- Jacks for Carriage-Painters use, of which thefollowing is a specification: V

This invention is an improvement on my patent of February 4, 1873, No.135,593; and consists, essentially, in the cross-bars or platform arms,which are constructed in one piece with the pivot, the ends of two ofthe bars furnished with an adjustable jaw and eccentric lever, and theother two with pins or claws for better holding the carriage-bodythereon, as hereinafter fully explained.

In the drawings, Figure l is a side elevation with wagon-body attached;Fig. 2, an end elevation, the arms in perspective; and Fig. 3, detailview of the eccentric and jaw.

A represents the standard or standards, and B the adjustablesector-wheel. In the socket 0 sets the pivot-pin d of the platform 0,havin g four arms, f f f f. These arms and pivotpin are cast in onepiece of metal, and swing around in any direction, and are held at anypoint, as shown in Fig. 2, by a thumb-screw, '6, which goes through thetop of the standard A, and through one side of the socket 0, and bitesagainst the pivot-pin d, holding it until loosened. The opposite ends ofthe platformarms ff are constructed with a slot, j, at right angles tothe arms, (see Fig. 3,) and in the slot is a movable jaw, 70, held by anut-screw or its equivalent, to adjust it according to the width of thestrip or piece Z, which is attached to the bottom of the wagon-body D,and by which the body is held on the platform 0. On the other side ofthis slot is pivoted a short eccentric lever, n, which presses and holdsthe other side of the strip 1 against the jaw 70.

The ends of the other two arms f f are provided with upright lugs orteeth g g, which are cast on andhold the sides of the wagonbody.

By these simple devices all wedges, grooves,

keys, 850., are done away with, and the whole my name in the presence oftwo subscribing witnesses.
